TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. A. McREYNoLDs, of Elkton, in the county of Todd,and State-rot' Kentucky, have invented a new and improved Table-Fan; andthat the following description, taken in connection with theaccompanying drawings, hereinafter referred to, forms a full and ex/actspecification ofthe same, wherein I have set lforth the nature andprinciples of my said improvements, by which my invention may bedistinguished from all others of a similar class, together with suchparts as I claim, and desire to have secured to me by Letters Patent.

This invention relates to an improved mechanism for operating a fan,designed more especially for keeping dies and other insects oif fromatable while meals are being eaten.

The invention consists in a peculiar construction and arrangement of theseveral parts, as hereinafter fully shown anddescribed. In the.`accompanying drawings- Figure 1 represents a side view ot' my invention.

Figure 2, a section pertaining to the same', taken in the linea: fc,fig. 1.

Similar letters of. reference 'indicate like parts.

A is a framing, constructed in any proper manner to support the workingparts, and B represents a train of wheels by which motion is transmittedfrom the driving or power-sbatte to the fau .or fans to be operated. Themotor is a weight, C, having a chain or cord, b, attached, which issecured to a drum, c, on the driving-shaft a, the chain or cord beingattached at its centre to the drum c. Each end of the chain or cordisprovided with a hook, d, on either of which the weight C may besuspended. D is a suspended or` swinging frame attached to the upperpart of the framing A, and having one or more fans, d', attached to itslower end. This fan has an oscillating or swinging motion imparted to itby means of a rod, E, connected with a crank-wheel F'on the last andmostrapidly-driven shaft of the train of wheels B. The rod E has apendant, G, attached at the point where it is connected to the frame D;and a weight. H., is secured to the lower end ofthe pendant. The rod Eis not attached directly or rigidly to the crank-wheel, but te a slide,I, fitted in a radial groove, e, in the crankwheel, and having a spring,f, bearing against it, said spring having a tendency to keep the slide Ipressed inward towards the centre of the crank-wheel F, as will be fullyunderstood by Areferring to iig. 2.

This device does not require to have the weight wound up; all that isnecessary to do when the weight is run 'down is to detach it from the`hook d it is on, and suspend it upon the other hook d, it beingunderstood that the chain or cord b is attached at its centre to thedrum c, and that when one hook is being drawn down 4under the action ofthe weight the other hookis being elevated.l This changing of the motoror weight from one hookto the' other,'otl course involvesa reversemovement of the train of wheels, but this is'of no consequence whatever,so far as this invention is concerned, the operating of the frame Dbeing precisely the saine under either direction in which the train ofwheels B may move. The weight H, attached to a pendant, G, of theconnecting-rod E, assists the crank-wheel F in passing its centres,while the attaching of the rod E to the slide I, governed by thespringf, obviates jarsand concussions, causing the devicc to runsmoothly, and with the least possible degree of wear and tear. Thisdevice may be constructed at a very moderate cost, and will prove veryeiicient in keeping ies and other winged insects o' from a table duringthe eating of meals.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- 1. The application of a. weight H to the rod E, whichdrives the oscillating fan-frame D from the crankwheel F of the train ofwheels B, for the purpose of assisting the crank-wheel past its centres,substantially as shown and described. i

.2. Attaching the rod E-to a slide, I, placed in a radial groove, e, inthe crank-wheel F, with -a spring, f, gearing against the slide, for thepurpose set forth. i

3. Attaching the chain or cord b at its centre t'o the drum c, andhaving a hook secured to each 'end of the shain or cord, to admit of theweight C being suspended to either end rof the chain or cord, when saidchain or cord, drum and weight, are used in combination 'with a train ofwheels, B, and a swinging or oscillating fan-frame, substantially as andfor the purpose specified. l

4. Thecombination and arrangement of the train of wheels B with theweight C, applied as shown, the oscillating fan-frame D, connected tothe crank-wheel F, and the weighted or loaded connecting-rod E,substantially as and for the purpose set forth.
